Abstract

AN ADAPTIVE CHANNEL EQUALIZER (50) FOR PROCESSING A DEMODULATED VSB SIGNAL CONTAINING TERRESTRIAL BROADCAST HIGH DEFINITION TELEVISION INFORMATION OPERATES ADAPTIVELY IN BLIND, TRAINING, AND DECISION-DIRECTED MODES. THE VSB SIGNAL IS CHARACTERIZED BY A DATA FRAME FORMAT (FIG. 2) CONSTITUTED BY A SUCCESSION OF DATA FIELDS EACH CONTAINING A DATA SEGMENT PREFACED BY A FIELD SYNC SEGMENT. EQUALIZATION IS EXPEDITED BY RECYCLING (35) RECEIVED TRAINING DATA THROUGH THE EQUALIZER MORE THAN ONCE DURING A VSB DATA FIELD AFTER A FIELD SYNC SEGMENT IS DETECTED.
